Malaysian Guidance on Biopharmaceutics Classification System (BCS) - Based Biowaiver

Effective from 1st March 2013, a biowaiver may be granted for generic immediate release oral solid dosage form products containing BCS Class I active ingredients listed in the Guidance On Biopharmaceutics Classification System (BCS) – Based Biowaiver documents. BCS Based biowaiver takes the three major factors that govern the rate and extent of drug absorption from immediate-release solid dosage forms into account i.e solubility and permeability of the drug substance/ active pharmaceutical ingredient (API), and dissolution characteristics of the drug product. This BCS approach provides an opportunity to waive in vivo pharmacokinetic bioequivalence testing for certain categories of immediate-release drug products.

Malaysian Guidance on Biopharmaceutics Classification System (BCS) - Based Biowaiver guideline is adopted mainly from the following guidelines to suit local requirements:

Guideline On The Investigation Of Bioequivalence (European Medicines Agency, London, 20 January 2010, CPMP/EWP/QWP/1401/98 Rev. 1/Corr)
Annex 7: Multisource (generic) pharmaceutical products: guidelines on registration requirements to establish interchangeability (World Health Organization (WHO), Technical Report Series, No 937, 2006)
Annex 8: Proposal to waive in vivo bioequivalence requirements for WHO Model List of Essential Medicines immediate-release, solid oral dosage forms (World Health Organization (WHO), Technical Report Series, No 937, 2006)
